Question

我是新手 - 我正在尝试在为用户加载变量时使用变量自动填充模态字段值。我有一种预感，我需要在加载时将.val（）添加到对话框中，但不确定。目前我正在尝试像标准表单一样加载值。感谢您提供的任何帮助 -

激活模式的按钮：

<input type="button" id="reply_clicky" name="emailmessage" onClick="updateReplyName('{{email.sender}}')" value="Reply" >

表格：

<div id="reply_form" title="Send Message">
<form id="replyemailform" method="POST" action="/sendemailmessage" name="emailposting">

    <p>
        <label for="recipient">To:</label>
        <input type="text"   name="recipient" id="recipient">
    </p>
    <p>
        <label for="subject">Subject: </label>
        <input type="text"  name="subject" id="subject">
    </p>
    <p>
        <label for="content">Message: </label>
        <textarea  name="content" id ="content"  class="textarea" rows="4" style=""></textarea>
    </p>

</form>
</div>

使用Javascript：

$(document).ready(function(){ 
    $('#reply_form').dialog({   
        autoOpen: false,
        height: 375,
        width: 350,
        modal: true,
        buttons: [
            {
            text: "Cancel",
            click: function() {
                $(this).dialog("close");
            }},
        {
            text: "Submit",
            click: function() {
                $('#replyemailform').submit();
            }}
        ]
    });
    $('#reply_clicky').button().click(function(e){
        $('#reply_form').dialog('open');
    });


}); 

function updateReplyName(sender){
console.log("updateReplyName function fired");
document.getElementById('recipient').value = sender;
}

编辑以包含DevlshOne的建议：

$(document).ready(function(){ 
    $('#reply_form').dialog({   
    autoOpen: false,
    height: 375,
    width: 350,
    modal: true,
    buttons: [
        {
        text: "Cancel",
        click: function() {
            $(this).dialog("close");
        }},
    {
        text: "Submit",
        click: function() {
            $('#replyemailform').submit();
        }}
    ]
});


$('#reply_clicky').button().click(function(e){
    $('#reply_form').dialog({
        open: function(e, ui) {
            $('#recipient').val('value is here');
        }
    });
    $('#reply_form').dialog('open');
});
});
